People can carry hazardous compounds from cigarette smoke that cling to their bodies and clothes and then release those compounds into non-smoking environments — exposing people nearby to cigarettes’ adverse effects, a new study shows.
For the last decade, third-hand smoke has been described as the residual contamination from cigarette smoking that adheres to walls and other surfaces in places where smoking has previously occurred. For example, hotels and rental car companies have implemented smoking restrictions to limit this contaminating odor from their rooms and cars.
